TL;DR: In this article, an improved technique for the measurement of temperature distributions in an EHD conjunction is presented, which employs the infrared radiation emitted by the EHD, and appears more rigorous, more reliable, and less cumbersome than that reported previously by the authors.

TL;DR: In this article, an infrared microdetector was employed to measure surface temperatures in elastohydrodynamic contacts with Hertz pressures up to 2 GPa, sliding velocities up to 6.0 m s−1 and rolling speeds up to 1.25 m s −1 with slide/roll ratios from −2 to +2.

TL;DR: In this paper, an infrared technique was used to determine the effects of load, speed and surface roughness on temperature in a sliding elastohydrodynamic (EHD) point contact.

TL;DR: In this article, moving surface temperature measurements in rolling and sliding EHD point contacts were made using an available infrared technique, and the film thickness and traction have also been measured, and it has been shown that while surface temperature rises in the low slip region, stationary surface temperatures are significantly higher than the moving surface temperatures.

TL;DR: In this article, the ferrograph was used to analyze wear debris generated in a sliding elastohydrodynamic contact and the amount of wear debris correlates well with the ratio of film thickness to composite surface roughness.
